SW3 Signal
Description
Default
(I2C mode)
4 DKEN
De-skewing enable.
I2C mode (ISEL=OFF)
DKEN pin must be set to OFF.
DK[3:1] pins are ignored and the De-skewing increments are selected through
the I2C interface.
Non I2C mode (ISEL=ON)
DKEN=ON:
then default De-skewing setting is used.
DKEN=OFF:
then DK[3:1] is used as the De-skewing setting.
OFF
7:5 CTL[1:3]

A[1:3]
/
DK[1:3]
The use of these multi-function inputs depends on the settings of ISEL and DKEN.
ISEL=ON, DKEN=ON:
General-Purpose Input CTL[1:3] pins are active, for backward compatibility.
These pins must be used to send DC signals only during the blanking time.
ISEL=ON, DKEN=OFF
DK[1:3] are active, these inputs are used to select the De-skewing setting for the
input bus.
ISEL=OFF, DKEN=OFF
A[1:3] are active, these bits are used to set the lower 3 bits of the I2C device
address.

RST#
I2C Interface Select.
ISEL=OFF:
I2C interface is active.
ISEL=ON:
I2C is inactive and the chip configuration is read from the configuration
strapping pins.
This pin also acts as an asynchronous reset to the I2C interface controller.
(Note)
When the I2C interface is active, DKEN must be set OFF.
OFF
Refer to the data sheet of SiI164BCT64 for detail.
